Who says the music industry is dead? Swift released her fourth studio album, Red, in October 2012 and sold 1.2 million copies in week one. The album’s first single, “We Are Never Ever Getting Back Together,” became her first to top Billboard’s Hot 100 chart. She parlayed that success into endorsement deals with Diet Coke, Sony and Covergirl, not to mention big bucks on the road. She should earn even more next year as she transitions from arena shows to stadium sellouts.
